Atmega 128

Introduction
ATMEGA128 is a big and one of the most feature rich AVR microcontroller from Atmel
featuring 128K Flash, 4K RAM, 53 I/O lines arranged in seven 8 bit ports, 8 ADCs, 2
UARTs, 4 timers, 8 interrupts and much more. ATMEGA128 Development Board
exposes all the pins of the microcontroller in neat PORT wise configuration. It is made
from double sided PTH PCB board to provide extra strength to the connector joints for
increased reliability. Board can work on 7 to 15V AC or DC supply.

 It has built-in reverse polarity protection. 7805 voltage regulator has heat sink for heat dissipation so
that it can supply 1Amp current continuously without getting over heated. It has switches
for boot loading, reset and power. It also has RS232 interface with DB9 female connector
based on MAX232. All the ports are connected to standard 10 pin FRC connectors.
